'The reinforcedand envelopedvcornposite strip is then fed through suitable rolls in the combining machine which compress the layers of the strip together so that the meeting ends of the paper-fabric layer form a flush'joint and the projections II are embedded in the adjacent surface of the board without protruding through the same into the fabric. It is to be understood, that the forming ofthe enveloped and reinforced strip shown in Figure 3 is produced vcontinuously bycombining the respective continuous layers I d and Iii-I5 as described.

. similar to that shown in Figure 2 and is enclosed The continuous laminated strip shown in Figj ure 3 is continuously combined in as describedy and fed through and from the combining apparatus to a forming instrumentality Il. This forming means comprises a lower roll I8 and`anupper roll I9 which engage the strip continuousr ly passing therethrough to form i. e. bentand shaped the same to the contour shown in Figure 5. The strip so formed continuously passes to av second forming instrumentality 29 comprisinga lower roll 2I;and an upper roll 22 which so engage the strip having the contour showniin Figure 5 that it is formed i. e. bent and shaped into nal channeLshape.y as shown in Figure 6. Itgwill ybe noted that the meeting edges or flush layer are disposed Within the bottom of the channel as shown in Figure 6.

The metal Working rolls I2, thevcombining rolls I3 and the forming and shaping instrumentalities I'I and I3 are positivelyroperated to draw. the continuous strip continuously through the several instrumentalitieaand from the forming instrumentalityZ, the strip is continuously f lapredeterrnined length of strip. It will be noted Athat this predetermined length of strip willin- `clude portions in continuous process ofuformation as shown in Figures 3 (flat) 5 (partially i bentand shaped) andi l(completely formed), and such length is drawn by the forming and shaping.instrumentalities II and 2i) through the same and shaped to final form. When the entire length of the predetermined strip has been given-the final channel shape as `shown in Figure 6, the advanced portion is brought into contact with the high speed rolls 26 `which rotate at a speed greater than that -of the rolls I2, I 3, I7 and and pass the finally formed channel run to a conveyor or box vfor shipment. When the remote end of the nally formed predetermined length of window run passes beyond the trip member 24, the latter descends to its former tripping position tobe engaged by the free end of the succeeding continuous length of channel run for accomplishingV the severing operation as just described. It is tobe understood, vthat the unsevered .following length of continuous strip continues tofeed forward after the severing of apredetermined length, to' be 'engaged by the forming .and shaping instrumentalities I 7 and 20, and that byreason of the Ymore rapidiremoval of the severed predetermined finally formed channel run through the medium of the highspeed rolls 26, thereis noopportunity for the in a layer of bituminized paper I4 as shown.

-The cloth covering layer I5, however, does not entirely enclose the construction, as is the case with the construction shown in Figure 3, but only l, one side, the ends vand the marginal edge portions of the other side; It will be noted that the cloth .joint formed by the free edges of the paper-fabric covers the joint 21 between the ends of the asphalt paper.

In forming the window run material of Figure 4, only the, paper orboard is fedfromvthe r oll I6 and the metal and paper are combined in the instrumentality I 3 in the manner previously described. rline cloth is fed from al separate roll 2B into combining relation with. the paperfenclosed metal strip and it is combined on the upper surface of the `same by an instrumentality similar to the instrumentality I3 so as to produce the construction shown in Figure 4 with the joint 2l concealed by the cloth layer. Thereafter, the operationof the machine isthe same as previously described.

` All of the instrumentalities described are operated from a single prime mover such as an electric motor whereby the speed of the rolls I2, I3, I'I and 22 is controlled'to give ka uniform feed, the rolls 26 being given a higherspeed through the medium of a suitable gear connectionand the punch 25 being actuated in its reciprocating movement byV a suitable clutch mechanism. It will be noted that a simple automatic machine is provided which isV quite'flexible, i. e., constructions both as shown in Figures 3 and 4 being .readily formed by simply connecting up the roll 28' and another combining apparatus I3.

It will thusbe seen Ifhave developed a method and machine of making Window run comprising continuously feeding a thin strip of metal I0 to a metal working instrumentality I2 and forming up-struck .projections II from the upper side thereof, and continuously feeding a Wider strip of non-metallic covering material I4- I5 into combining relation with the metal strip. The metal strip is superposed upon the wider non-metallic strip in longitudinally centered relation thereto and the transversely extended portionsof Vthe non-metallic strip are' folded so as to enclose the upper surface ofI the metallic strip vfrom which they projections 'II extend. In the combining instrumentality the composite or laminated strip, i. e., the metalstrip enclosed' in the paper-fabric strip is compressed and the projections are causedto enter ory engage the non- `metallic material, namely, the paper, but do not tently actuated, Without interrupting the continuous constant feeding movement of the independent and composite strips. As heretofore pointed out, when a predetermined length is severed, a part of it has been formed to final channel form as shown in Figure 6 While the remainder is undergoing formation in the instrumentalities il and 2d. When one of these lengths has been completely formed, itsv advance end Will have reached the high speed rolls 2@ and at the saine time, its remote end will have passed beyond the movable trip member 2d which returns from its moved position to be engaged by the constantly fed and formed advancing continuous channel strip, so that the repeated operation of severing the continuous channel strip into predetermined lengths is carried out. This ntermittent automatic severing operation, as explained, does not result in any interruption of the constant feeding of the strip material either of the independent strips or the combined or composite strip or channel. These all move at a constant speed While the rolls 26 operate ata greater speed on the completed length of Window run and thereby clear the machine of one predetermined length of material substantially simultaneously with the severing of the next consecutive predetermined length from the continuous strip. The provision of the trip member affords an intermittent and automatic means for actuating the punch and also assures that the constantly fed strip Will be severed in uniform predetermined lengths.

In making the channel shown in Figure 4, the operation of the machine is the same, except as stated, the soft layer is independently fed and combined With the metal layer and the fabric layer is independently fed at the same constant speed of the other instrumentalities, but on the upper surface of the composite strip of metal enclosed in bituminized paper, as shown in Figure '7 Where two similar combining apparatuses I3 are used. This fabric layer is of greater Width than the composite strip and its transversely extended portions are folded about the same as shown in Figure 4 to cover one surface, the ends, and the marginal areas of the opposite surface and conceal the joint 21 between the meeting ends of the paper layer. In the channel formed from this material, the fabric layer lines the interior wall of the channel.

I have referred herein to paper which is relatively thick or of thin board-like character, and

in calling for paper in the claims, I mean to.

include this type of material as Well as equivalent paper-like products. Also, I have mentioned that the paper is bituminized, i. e., is impreg nated or coated, or both, with a suitable bitumen such as asphalt. Such paper will have an adherent surface to Which the cloth will permanently adhere, and also the bitumen will have an adherent function between the paper and the reinforcing metal layer. In this connection, a separate adhesive may be used to adhere the cloth to the paper in some cases. It is, however, preferred to use a bituminized paper or a paper which is weather and Wear-resistant and not affected by water or moisture as Well as extremes in temperature.

The method and apparatus herein described are useful also in forming Window channel run in which the non-metallic covering layer comprises cork composition, i. e., comminuted cork united by a binder in lieu of the paper, adhesively united to a suitable textile or other fabric backing.

In some cases, and referring particularly to Figure 4, the covering layer I5 instead of being made of fabric, is made of thin sheet metal as, for example, steel band. Such a Window run material can be readily produced by the aforesaid method and apparatus, the strip of metal being fed from the roll 28 and combined and formed in the manner described.

I claim:

1. Method of making Window run comprising continuously feeding a strip of substantially nat thin sheet metal to a metal working instrumentality and forming up-struck projections providing perforatio-ns, continuously feeding a wider strip of substantially flat fabricated covering material and soft material into which said projec tions may embed themselves into combining face to face relation with the perforated metal strip by bringing the soft material and metal into surface contact, centering the metal strip longitudinally upon the said soft material and the covering strip and folding over the flat portions of the same extending transversely beyond the edges of the metal strip to enclose the metal strip, compressing the layers of the composite strip and causing the projections to enter and be embedded in the said soft material, bending the composite strip along longitudinal lines and shaping the composite strip to Window run contour at one end, the independent strip material and the composite strip being continuously fed at uniform speed, severing predetermined lengths from said composite strip at a flat portion thereof while continuously feeding, combiningl bending and shaping other portions 0f the same strip, and thereafter completely formingV the remainder of the severed portion of the strip to the same contour.

2. The method in accordance with claim 1 in which the covering strip and soft material are fed as a combined unitary strip.

3. The methodin accordance with claim l in which the covering strip and the soft material are separately fed and combined.
